Hey. I am planning to build a temperature sensor network using esp32 devices. I am wondering what are the best sensors to use (most accurate, fastest response and overall) for the IOT projects.
I have read about BMP180/BMP280
DS18B20
LM35
DHT22
Myself, I have only tried DHT22 sensor but was quite dissapointed with the results. The response time was extremely slow (im not sure whether thats how temperature sensors supposed to work), but when I take this sensor from indoors to outdoors (10 degrees celcius difference) it takes like 5 minutes to reach the outdoors temperature.
I am planning to maybe grab one or two DS18B20 sensors and see how they behave.
From your own experience, what would you use for IOT projects? Do you have your personal favourite when it comes to measuring temperature>?
